Why choose Signature GYN for your Clinical Trial?

As the PI of our site, I work closely with my staff throughout all aspects of our trials including
  • Trial selection
  • Site qualification visits
  • Prescreening of patients
  • Development of source documents and site SOPs
  • Site initiation visits
  • I personally perform the needed assessments at each visit as well as meet with patients at other visits to monitor patient progress and assess AEs
  • Monitor visits audits and close out visits
  • Because of the size and structure of our site, decisions can be made quickly.  There are no committees or boards that must give approval.  Decisions and paperwork can be turned around in a few days, not weeks or months, so we can work efficiently with sponsors and be responsive to your needs. 
Many of our study subjects are recruited from our current, diverse patient base.  Our office is already convenient and accessible to them thus improving compliance, retention and follow up.  And with a single provider, there is a greater consistency in evaluations and assessments. In summary, we are uniquely positioned to meet and exceed our recruitment goals producing quality data in a timely fashion.
Yours truly, 
John Whitfield, MD
